Definitions

• the present invention relates to a disposable and sterile fluid or particulate applicator. It has particular application in the medical and food technologies where the supply of a fluid or particulate under sterile conditions is paramount.
• Single use containers have been known to be used to provide a sterile fluid or particulate.
• such containers may provide a saline solution to wash wounds, may contain sauces to be added during cooking or may house materials that can not be exposed to air.
• multi-use containers such as sauce bottles are also known where they may be used many times and even be refillable.
• multi-use containers also include a tool to assist in dispensing of the fluid or particulate.
• These tools such as nozzles, can become contaminated through continued usage. Remnants of the fluid or particulate can remain in the nozzle and can over time start to degrade.
• the nozzle can become blocked if it is in physical contact with a food during use, such as the application of sauce internally to a pie. Not only is the blockage inconvenient, but it can pose a health risk.

• FIGS 1 -3 a fluid dispenser 10 according to a first embodiment of the invention that may be used to dispense liquids such as tomato sauce.
• the dispenser 10 includes a tool 12 that divides the dispenser into a reservoir 14 and a cover 16.
• the tool in this embodiment being a spout, is sealingly circumferentially attached to the inside of the dispenser around internal radius 18 to prevent any fluid in the reservoir flowing into the cover except through an aperture in the spout.
• the cover simply needs to be removed from the reservoir at a location forward from said radius. This can be done by the use of an external cutting tool, such as a pair of scissors.
• a seam 20 may be introduced forward of the radius, such as that made by a heat seal, which allows the cover to be physically torn from the reservoir thereby exposing the spout.
• the dispenser To manufacture the dispenser one therefore simply needs a single sachet into which is introduced and fixedly attached spout 12, and whereby a heat seal 20 is then applied forward the location where the spout 12 is fixed to the dispenser 10 to enable the cover 16 to be frangibly attached to the reservoir 14 .
• the aperture 22 of the spout may be appropriately sealed, although a particular seal is not shown.
• the cover may also assist in the sealing but that is discussed in a further embodiment.
• two sheets of suitable material such as plastic, may be positioned one over a spout and one under a spout and whose edges 24 are then heat sealed to thereby define the dispenser.
• the cover 16 is torn along the frangible seam 20 to thereby expose spout 12 and aperture 22.
• fluid is caused to flow out through said aperture 22.
• the spout 12 may be manufactured so as to be more resilient than the rest of the dispenser 10 and thus can be adapted to be inserted into food, such as pies and pasties, so that sauce can be dispensed directly into the pies or pasties. Once the sauce has been dispensed, the dispenser is disposed of eliminating problems of public health. Since the spout is completely covered by the cover prior to its use it is kept in a sterile environment.
• FIG. 4-6 there is shown a second embodiment of the invention where a spout 12 is manufactured integrally with the reservoir 14.
• the cover 16 is removably attached to the reservoir 14, with the seam 20 once again being one allowing the cover to be torn from the reservoir.
• the cover also includes a cavity 26 correspondingly shaped to the spout and including an end 28 that is adapted to sealingly engage the aperture 22 to prevent fluid 28 flowing into the cover member when it is attached to the reservoir.
• Spout 12 is slidably disposed within the reservoir. Located towards the spout end of the reservoir is a join or seam 20 dividing the dispenser into a reservoir 14 and cover 16. The edge 30 of the reservoir includes an opening 7
• the spout 32 positioned to be co-axial with the spout 12.
• the opening 32 is exposed.
• the spout can then slide through the opening. Obviously the edges of the spout remain in sealing engagement with the reservoir to ensure that any fluid within the reservoir can only flow through the spout.
• To use the dispenser one simply tears the cover exposing the opening and then applies pressure to the reservoir behind the spout which pressurises the reservoir causing the spout to move through the opening until its size is equal to that of the opening at which point the fluid is pressurised to flow out through the spout.
• the spout may also be manufactured from a hard material enabling more control over the insertion of the nozzle into food by being manufactured of a resilient material.
• the dispenser 10 includes a bladder 34, one end of the bladder 34 being foldable along folds 36 and including a spout 12.
• the bladder is enclosed by the reservoir 14 and cover 16 that are integrally attached to each other and define the outside of the dispenser.
• the cover 16 is tearingly removable to expose the side of the reservoir and through which can then extend the spout 12.
• the reservoir containing the fluid is pressurised acting on the spout that is then moved outwardly until the folds are straightened.
• the nozzle may be manufactured of resilient material allowing the spout to be inserted into foods such as pies.
• Figures 9- 11 shows a bladder
• the foldable portion 36 may simply be attached to the inside walls of the reservoir 14 without extending throughout the whole bladder.
• the exact configuration would of course depend upon what strength the bladder needs to be manufactured to and the cost and ease of manufacture.
• a fifth embodiment of the invention can be seen in Figures 12 and 13 where the spout is an integral part of the reservoir.
• the cover is tearingly or frangibly attached along seam 20 to the spout portion of the reservoir.
• This embodiment may be useful in situations where the spout need not be inserted into matter but where it is imperative that the outside of the aperture is kept sterile.
• the aperture 22 is sealed by plug 38 that is not attached to the cover. To break the seal instead of removing the cover and then the plug., the plug may be twisted by, for example, applying rotational motion 40 to the plug through the cover thus breaking the seal on the aperture. Only then is the cover 16 removed thereby removing the plug 38 and exposing the spout 12. 8
• FIG. 14 and 15 Shown in figures 14 and 15 is a sixth embodiment of the invention where the cover is frangibly attached to the reservoir and where the cover 16 is correspondingly shaped to the spout 12.
• the cover is frangibly attached to the reservoir and where the cover 16 is correspondingly shaped to the spout 12.
• FIG. 16 and 17 Yet a further embodiment of the invention can be seen in Figure 16 and 17 whereby besides the cover protecting a spout for the dispensation of fluid or particulates, the cover may also accommodate tools that may assist in a particular application.
• tweezers 42 including a base 44 adapted to seal aperture 22.
• the cover 16 is of a larger construction so as to accommodate the tweezers 42 which are kept in a sterile environment.
• This embodiment may have particular application for the medical field where tools such as tweezers that may be used to treat wounds need to be kept in a sterile environment.
• the reservoir may include a saline solution that may be used to wash the wound.
• the dispenser not only provides the sterile saline solution but also tweezers that may assist in cleaning the wound. Both are kept in the one dispenser and are thus not only convenient but are used only once minimising risk of infection.
